The renowned US food delivery platform, DoorDash, has recently rolled out a cutting-edge food delivery robot called Dot. Dot represents a four-wheeled, autonomous driving marvel, standing at roughly 1.37 meters in height. It boasts a sophisticated perception system, incorporating multiple cameras and radars, enabling it to sense its surroundings and navigate with precision. This compact and highly agile robot can comfortably house six large pizza boxes within its interior, while its maximum load capacity reaches an impressive 13.6 kilograms. Moreover, DoorDash has ingeniously introduced an intelligent weighing feature, which has led to a remarkable 30% reduction in complaints regarding missing items. Prior to this, the company had already taken strides in the autonomous delivery arena, and the introduction of Dot is strategically aimed at bridging the gap in market-fit scenario solutions.
